// This script is originally from github.com/olofhellman/VerifyNoBS

// The idea is that all build settings should be kept in .xcconfig files,
|
|
// rather than in the xcode pbxproj file inside an Xcode project bundle
|
|
// Having the script run as part of a regular build ensures that the project file
|
|
// doesn't accidentally accumulate build settings
